Lentils |
255 g |
Milo |
300 g |
What is the difference between the total mass of noodles collected and the total mass of milo collected? Give your answer in kg.
(a)
Number of packets of lentils collected= 1 u
1 u = 12
Total number of packets of food items collected
= 6 u
= 6 x 12
= 72
Number of packets of flour collected
= 72 - 14 - 12 - 24
= 22
(b)
Total mass of noodles collected
= 14 x 445
= 6230 g
Total mass of milo collected
= 24 x 300
= 7200 g
Difference between the total mass of noodles and the total mass of milo collected
= 7200 - 6230
= 970 g
1000 g = 1 kg
970 g = 970 ÷ 1000 = 0.97 kg
Answer(s): (a) 22; (b) 0.97 kg
